“An Israeli general has raised the possibility of creating a buffer zone in Syria, in cooperation with local forces wary of jihadist fighters, should President Bashar Assad be toppled... Syrians "with a common interest in cooperating with us" against radical Islamist fighters would be Israel's natural allies in any such security zone, Golan said. "If an opportunity presents itself -- and it hasn't as yet -- we should not hesitate," he said. "Everything should be done wisely and secretly, with a true examination of where the interests of the other side lie."”
